[Qemu-devel] [PATCH v4 0/6] pci: multi-function bit fixes

[Isaku Yamahata]

Changes v3 -> v4:
- introduced multifunction property and add validation check to catch
  user operation errors.
- some more clean up.

patch description:

When pci devices are populated as multi-function,
OS can fail to probe function > 0. It's because multi function
bit of header type register in configuration space isn't set,
so OS probes only function 0 skipping function > 0 as optimization.

This patch set make qemu set multi function bit when function > 0 
is populated.


Isaku Yamahata (6):
  pci: use PCI_DEVFN() where appropriate.
  pci: remove PCIDeviceInfo::header_type
  pci: set PCI multi-function bit appropriately.
  pci: don't overwrite multi functio bit in pci header type.
  pci: use pci_create_simple_mf()
  pci_bridge: make pci bridge aware of pci multi function bit.
